Getting Energized?

Oh my I for some reason lately need some good suggestions for this. I am so tired here lately, but I am hoping that it will subside after I get used to the school year just starting and my work schedule change. But for now I will just have to depend on my diet dr. peppers and Crystal Light Energy mix, because I have no guts to try a real energy drink I am too afraid of what they might taste like. So anyone who reads this post tell me: What you do to get more energized and to make through the day without a nap?
